[SPARK-15722][SQL] Disallow specifying schema in CTAS statement
## What changes were proposed in this pull request?
This is no longer allowed:
```
sql("CREATE TABLE blocks (name STRING, age INT) AS SELECT * FROM boxes")
```
This previously loaded data into the wrong columns if the schemas of
`blocks` and `boxes` don't match. We should just always use whatever columns
are projected as the schema.
## How was this patch tested?
